财产＆＃39; ReportSource＆＃39;是'ReadOnly＆＃39;

Question

我目前正在VB.net上发布报告，但我发现了这个错误：

    Property 'ReportSource' is 'ReadOnly'.

这是我的代码：

   Imports CrystalDecisions.CrystalReports.Engine

导入CrystalDecisions.Shared

Public Class MRTable

Private Sub ToolStripButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton1.Click
    Dim cryRpt As New ReportDocument

    cryRpt.Load("D:\Orly\workspace\HMIS\01.26.15\HoMISv2.0\CRMedicalRecords.rpt")

    Dim crParameterFieldDefinitions As ParameterFieldDefinitions
    Dim crParameterFieldDefinition As ParameterFieldDefinition
    Dim crParameterValues As New ParameterValues
    Dim crParameterDiscreteValue As New ParameterDiscreteValue

    crParameterDiscreteValue.Value = Nurse.SelectedPatient
    crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields
    crParameterFieldDefinition = crParameterFieldDefinitions.Item("PCode")
    crParameterValues = crParameterFieldDefinition.CurrentValues

    crParameterValues.Clear()
    crParameterValues.Add(crParameterDiscreteValue)
    crParameterFieldDefinition.ApplyCurrentValues(crParameterValues)

    CRMedicalRecords.ReportSource = cryRpt
End Sub

结束班

我希望你能帮助我。

请在Crystal Reports或Visual Studio中打开报告，然后在下面进行检查 文件＆gt;报告选项 选项Read-Only被关闭。

正如您在添加参数时所做的那样，这可能会阻止您编辑报表。
